Which statement describes the behavior of the function f (x) = StartFraction 2 x Over 1 minus x squared EndFraction? f (x) = StartFraction 2 x Over 1 minus x squared EndFraction

B. The graph approaches 0 as x approaches infinity.

Step-by-step explanation:

The function f(x) is:

f(x) = (2x)/(1-x^2)

When x approach infinity the term x² grows rapidly (more rapid than x), thus 1 - x², which is in the denominator will decrease, become a large negative more rapid than the x in the numerator. Thus you can expect that the function approaches zero.

2x^2+5x+17
